This brings us down to the power unit itself. The Mach 1 will appear to be quite plain from the outside, with only this one label breaking up the honeycomb ventilation panel. Of course, when the unit is powered on, the light from the LED fan will emanate through, adding a soft glow to the back of your enclosure.

     This is the real business end of the Mach 1. For the photo, I've removed all of the rubber dust caps from the power connectors. Naturally,  you'll want to leave those caps on any power-ports you're not actually utilizing. Notice the label above the ports on the left. This label pretty much spells out where you hook up your power leads. The PCI-E are 4-pin connectors while everything else is a 5-pin. Just in case you aren't the type that actually reads the instructions, the power connectors themselves are constructed so they will only go on their respective port.

     The warning on the right says something to the effect that pulling a power lead out of its connector while the power supply is operating -- would be bad! While the label says that damage to components could result, I would be willing to bet you could end up feeling a little bit of that mistake on your hand too.

     The good thing is, those connectors are pretty secure if you install them correctly. Each one is held in place by a coarsely threaded connector, which makes it quick to turn and difficult to cross thread. They are spaced far enough apart that you shouldn't jam your knuckles trying to get all of the connectors installed.

     Here is the power spec panel from the Mach 1. We arrive at 1000 watts by adding the six +12 volt rails together with the +3.3 and the +5 volt rails.  Using Ohms Law, you can calculate the power availability or consumption yourself using very a basic mathematical formula. W (power) = I (current) x V (voltage). With this model of the Mach 1, each 12 volt rail can produce 240 watts of power. That's not to say that it's going to be generating that much power all the time. While the voltage (12volts) will remain constant, the current load (or amperage) will fluctuate based upon the needs of the components hooked to it.

     The unit will draw cooling air to  itself with this 150mm LED fan. The fan is located on the bottom of the unit. This fan should also help to increase airflow inside your enclosure.
